JUNIPER-EX-MAC-NOTIFICATION-MIB
Updated Apr 28, 2010AI MIB Summary
The JUNIPER-EX-MAC-NOTIFICATION-MIB configures and triggers SNMP traps on Juniper EX series switches to notify management systems of dynamic MAC address additions and removals within the device's forwarding database. This mechanism enables real-time monitoring of Layer 2 topology changes and MAC table instability by exposing specific MAC notification events rather than static interface statistics.
This MIB module is for configuration of the MAC notification feature. MAC notification is a mechanism to inform monitoring devices when there are MAC addresses learnt or removed from the forwarding database of the monitored devices.

jnxMacNotificationMIBThis MIB module is for configuration of the MAC notification
feature. MAC notification is a mechanism to inform monitoring
devices when there are MAC addresses learnt or removed from
the forwarding database of the monitored devices. MODULE-IDENTITY .1.3.6.1.4.1.2636.3.40.1.7.1 |

jnxMacNotificationMIBGlobalObjects OBJECT IDENTIFIER .1.3.6.1.4.1.2636.3.40.1.7.1.1.1 |
jnxMacGlobalFeatureEnabledIndicates whether the MAC notification feature is currently
running in the device.
Setting this object to false(2) disables the MAC notification
feature globally.
Setting this object to true(1) will start the MAC notification
feature running in the device. If the feature is already
running, setting to true(1) has no effect.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.1 |
jnxMacNotificationIntervalThis object specifies the maximum interval of time between
jnxMacChangedNotifications being generated by the device.
If the value of jnxNotificationsEnabled is true(1), the
device will send out the generated jnxMacChangedNotifications
and archive the MAC change notification events in the
jnxMacHistoryTable. If the value of jnxNotificationEnabled is
false(2), the device will not send out the generated
jnxMacChangedNotifications but it will archive these events
in the jnxMacHistoryTable.
If the value of this object is equal to 0, the device will
generate jnxMacChangedNotifications and archive the MAC
change notification events in the jnxMacHistoryTable as soon as
there is MAC address learnt or removed by the device.
If the value of this object is greater than 0, the device will
wait for a period of time equal to the value of this object
before generate the jnxMacChangedNotifications and archive
the MAC change notification events in the jnxMacHistoryTable.ro Unsigned32 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.2 |
jnxMacAddressesLearntIndicates the number of MAC addresses learnt by the
device.ro Counter64 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.3 |
jnxMacAddressesRemovedIndicates the number of MAC addresses removed from the
forwarding database.ro Counter64 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.4 |
jnxMacNotificationsEnabledIndicates whether jnxMacChangedNotification notifications
will or will not be sent when there are MAC addresses
learnt or removed from the device's forwarding database.
Disabling notifications does not prevent the MAC address
info from being added to the jnxMacHistoryTable.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.5 |
jnxMacNotificationsSentIndicates the number of jnxMacChangedNotifications sent out
by the device.ro Counter64 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.6 |
jnxMacHistTableMaxLengthThe upper limit on the number of entries that the
jnxMacHistoryTable may contain. A value of 0 will
prevent any history from being retained. When this
table is full, the oldest entry will be deleted and
a new one will be created.ro Unsigned32 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.7 |
jnxMacHistoryTableThis table will archive the MAC change notification events
generated by this device. The MAC change notification
events are archived here even if jnxMacChangesNotifications
are not actually sent. SEQUENCE OF JnxMacHistoryEntry .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.8 |
jnxMacHistoryEntryA MAC change notification message that was previously
generated by this device. Each entry is indexed by a message
index. JnxMacHistoryEntry .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.8.1 |
jnxHistIndexAn index that uniquely identifies a MAC change notification
event previously generated by the device. This index starts at
1 and increases by one when a MAC change notification is
generated. When it reaches the maximum value, the agent wraps
the value back to 1. Unsigned32 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.8.1.1 |
jnxHistMacChangedMsgThis object contains the information of a MAC change
notification event. It consists of several tuples packed
together in the format of '<tuple1><tuple2>...'.
Each tuple consist of 13 octets in the format of
'<operation><VLAN><MAC><dot1dBasePort>' where
<operation> is of size 1 octet and supports the following values
0 - End of MIB object.
1 - MAC learnt.
2 - MAC removed.
3 - MAC updated.
<VLAN> is VLAN number of the VLAN which the MAC address is
belonged to and has size of 2 octet.
<MAC> is the Layer2 Mac Address and has size of 6 octets.
<dot1dBasePort> is the value of dot1dBasePort for the
interface from which the MAC address is learnt and has size
of 4 octets.ro OCTET STRING .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.8.1.2 |
jnxHistTimestampThe value of sysUpTime when the jnxMacChangedNotification
containing the information denoted by the jnxHistMacChangedMsg
object in this entry was generated.ro TimeTicks (SNMPv2-SMI) .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.8.1.3 |
jnxMacAddressesUpdatedIndicates the number of MAC addresses updated by the
device.ro Counter64 .1.3.6.1.4.1.2636.3.40.1.7.1.1.1.9 |
jnxMacNotifications OBJECT IDENTIFIER .1.3.6.1.4.1.2636.3.40.1.7.2 |
jnxMacNotificationsPrefixAll Mac Notifications are registered
under this branch. OBJECT IDENTIFIER .1.3.6.1.4.1.2636.3.40.1.7.2.0 |
jnxMacChangedNotificationThis notification is generated when there is enough MAC
address information to fully occupy a maximum size SNMP trap
message. This notification is also generated when there
is at least one MAC address changed or removed and the amount
of time elapsed from the previous notification is greater
than the maximum wait time denoted by
jnxNotificationInterval object.
If there are more MAC addresses information than can fit into
one cmmHistTrapContent object, then multiple notifications
will be generated. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.40.1.7.2.0.1 |
